A process for the preparation of derivatives of halo-but-2-enoic acids and esters high in 2-ene content, several of which are novel. The esters and their derivatives are useful as promoters for the polymerization of ethylene or the copolymerization of ethylene with alpha -olefins and, optionally, nonconjugated polyenes. The promoters can also be combined with transition metal compounds, e.g., vanadium, to form combination promoter-catalyst compounds.
